Ranges are a convenient and space saving way to write a vector with evenly
spaced elements.

Or this space saving way ONLY works for double, not for floats and not (even)
for integers.

Example:

if optimize_range ()
  printf("Range is space saving optimized.\n");
else
  printf("Range is NOT space saving optimized.\n");
endif
Range_Double = double(1):double(100);
Range_Single = single(1):single(100);
Range_int64 = int64(1):int64(100);
Range_uint64 = uint64(1):uint64(100);
Range_int8 = int8(1):int8(100);
Range_uint8 = uint8(1):uint8(100);

whos

Range is space saving optimized.

         Range_int8        1x100                      100  int8
         Range_uint64      1x100                      800  uint64
         Range_uint8       1x100                      100  uint8
